how do you tie a big christmas bow

It's quite simple, actually. First, you need a piece of ribbon that is long enough to wrap around the present at least twice. Then, you need to make a loop with the ribbon and hold it in one hand. Next, you take the free end of the ribbon and wrap it around the present a second time, going over the loop you made in the previous step. Finally, you pull the free end of the ribbon tight and tie it in a knot to secure the bow in place.
